Dunno, mine's aircooled. But there is likely an exact specification for coolant for your bike and mixing coolant types could be very bad for your cooling system. A friend mixed different types in his car and it blew the water pump in just a few months. Suggest you see what the dealer recommends and now might be a good time to drain and fill the entire system, after you fix the leak of course.I have a small coolant leak and am wondering if i can replace it with the same type I use in my cars after the repair. THX fer ur help ya'll!!!
